As of early 2026, the cost for a one-way trip from Charles de Gaulle (CDG) Airport to central Paris (including the Eiffel Tower area) is €14.00. This fare applies to the RER B train, which is the most direct rail link into the city. You cannot use a standard €2.55 "Ticket t+" for this journey, as the airport is located in Zone 5. Once you arrive at a central hub like Saint-Michel Notre-Dame or Denfert-Rochereau, your €14.00 ticket allows for a free transfer to the Metro (Line 6 or Line 9) to reach the Eiffel Tower stations (Bir-Hakeim or Trocadéro). For tourists staying multiple days, the Navigo Semaine (weekly pass) at €32.40 or a Paris Visite pass may be more cost-effective as they include airport transfers. It is worth noting that paper tickets have been largely phased out in favor of the Navigo Easy card or digital tickets on your smartphone. If you prefer a taxi, fixed flat fares remain in place, currently costing approximately €55 to the Right Bank and €62 to the Left Bank (where the Eiffel Tower is located).
